If you’re a fan of aquarium sealife, you’ve probably heard of the 20 long aquarium. But just how big is it, and what kind of sealife can you keep in it? As an avid aquarium enthusiast, I’ve had personal experience with the 20 long aquarium and can provide some insights.

What is a 20 long aquarium?
A 20 long aquarium is a rectangular tank that measures 30 inches in length, 12 inches in width, and 12 inches in height. It’s a popular choice for hobbyists who want a tank that’s bigger than a standard 20-gallon tank but not as large as a 40-gallon tank. The 20 long aquarium can hold 20 gallons of water, hence the name.
What kind of sealife can you keep in a 20 long aquarium?
Despite its relatively small size, a 20 long aquarium can accommodate a variety of sealife. Some popular options include:
Small fish, such as tetras, guppies, and rasboras
Shrimp, such as cherry shrimp and ghost shrimp
Snails, such as nerite snails and mystery snails
Live plants, such as java ferns and anubias
It’s important to note that while a 20 long aquarium can hold a decent amount of sealife, it’s still a relatively small tank. Overcrowding can lead to poor water quality and health problems for your sealife. Be sure to research the specific needs of the sealife you plan to keep and make sure they’re compatible with each other.
Setting up a 20 long aquarium
Setting up a 20 long aquarium is similar to setting up any other aquarium. You’ll need to:
Choose a suitable location for your tank
Install a filter and heater
Add substrate and decorations
Cycle your tank before adding sealife
One thing to keep in mind is that a 20 long aquarium has a smaller surface area than a standard 20-gallon tank. This means that gas exchange can be more difficult, which can lead to low oxygen levels in the water. To combat this, make sure your filter is providing adequate surface agitation.
